No, you cannot get this in the GTA, or Ontario for that matter (yay, LCBO!). I have bought other beers from that brewery in Buffalo though.

Without heading the Buffalo, the closest options may be Rogue Hazelnut Brown Nectar, Black Oak Nut Brown or Samuel Smith's Nut Brown. All of these are available at the LCBO, just do a search at LCBO.com for the locations of them.

If you're looking for a rich holiday beer with a high ABV content, you'll want to keep a lookout for Aventinus Eisbock or Samichlaus. Neither is in stock at the LCBO at the moment, but I'll be very surprised (and disappointed) if they aren't restocked by Christmastime.
